Dry steam exists almost entirely in a vapor state and contains very little suspended water droplets. In other words, it is essentially water in its purest, gaseous form. Dry steam can be safely used for cleaning areas that cannot be exposed to water, delicate areas and spaces or equipment that can’t be exposed to water. Dry steam effectively kills harmful allergens and bacteria, leaving surfaces dry and ready for use.
In this guide, learn more about dry steam and how it enables efficient, safe cleaning in various industrial applications.
Moisture Content
Distinguishing dry steam, saturated steam, and other types of steam used in industrial cleaning involves understanding moisture content. Heating steam to the boiling point will produce saturated steam.
Saturated steam is not fully dry, and typically contains a moisture content between 3% and 5%. Dry steam is considered steam with less than 5% moisture and superheated steam is heated beyond the boiling point, which removes any remaining moisture before the steam reaches its point of use. This is why dry steam and superheated steam are ideal for various industrial applications that involve cleaning, sanitation, fast drying, or controlled curing.
Operating Pressure
Steam has a direct correlation between temperature and operating pressure. As the pressure of the steam grows, so does its corresponding boiling point temperature. For example, at standard atmospheric pressure (14.7 PSIA), the boiling point of water and the temperature of saturated steam is 100 °C (212 °F).
Dry superheated steam does not have a direct relationship between pressure and temperature, meaning it can exist at a wide range of temperatures at different flow rates and pressures.
Superheated steam is hotter and has lower density and specific enthalpy, making it more stable for flow measurement. Flow rates for superheated steam can often be higher and have a wider velocity range compared to saturated steam.
Flow pressure determines the temperature of steam, and the kilowattage (kW) determines its output – meaning, for example; 10kW at 34.5 lbs/hr can be delivered at either 15 psi, 80 psi, or 165 psi. Under pressure, all types of steam maintain their temperature but those temps will begin to drop as it is released at the point of use.
Our TruBlu Dry Steam Cleaners
Electro-Steam is the only authorized manufacturer that offers true after-heated (superheated) steam systems, delivered via our on-board ASME-approved and stamped superheater unit. Our TruBlu portable dry steam cleaners offer a chemical-free, powerful solution that can significantly reduce time spent on cleaning tasks, effectively lowering labor costs. Carrying the ASME designator “S” stamp, TruBlu is ASME code compliant for use in the United States and meets Canadian standards.
Unlike conventional wet cleaning methods, which have the potential to flood flooring and create dangerous contamination risks, TruBlu’s dry vapor steam cleaning process prevents moisture-related equipment damage, reduces allergen buildup, and ensures superior sanitation.
